Abstract
- Background: Fasting blood glucose (FBG) variability, an emerging marker of glycemic control, has been shown to be related to the risk of cardiovascular events and all‐cause mortality in subjects with or without diabetes. However, whether FBG variability is independently associated with a higher all‐cause mortality in heart transplant recipients remains unknown. Methods: We performed a retrospective cohort study including 373 adult recipients who survived for at least 1 year after heart transplantation with a functioning graft and measured FBG more than three times within first year after transplantation. Multivariable adjusted Cox regression analyses were performed to assess the association between FBG variability and all‐cause mortality. Results: Patients were categorized into three groups according to the coefficient of variation of FBG level: ≤7.0%, 7.0%–13.5%, and >13.5%. During a median follow‐up of 44.4 months (interquartile range [IQR], 22.6–63.3 months), 31 (8.3%) participants died. In univariate analyses, FBG variability was associated with an increased all‐cause mortality (hazard ratio [HR]: 3.00, 95% confidence interval [CI]: 1.67, 5.38; p <.001). This association remained materially unchanged in the multivariable model adjusted for components of demographics, cardiovascular history and lifestyle, hospital information, immunosuppressive therapy, and post‐transplant renal function (HR: 2.75, 95% CI: 1.43, 5.28; p =.004). Conclusions: After heart transplantation, high FBG variability is strongly and independently associated with an increased risk of all‐cause mortality. Our findings suggest that FBG variability is a novel risk factor and prognostic marker for heart transplantation recipients in outpatient clinic. [ABSTRACT FROM AUTHOR]
